SWITCH-STAN D.

SPECIFICATION forming part of Letters Patent No. 724,659, dated April 7,1903. Application filed October 9, 1902. serial No. 126,496. (No model.)

To (ZZZ whom it may concern:

Be it known that I, ARTHUR B. BELLOWS, a

citizen of the United States, residing at Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented or discovered certainnew and useful Improvements in Switch-Stands, of which improvements thefollowing is a specification.

The invention described herein relates to certain improvements in a formor construction of switch-stand forming the subject-matter of anapplication filed September 3, 1902, and numbered serially 121,949.

The invention is hereinafter more fully de scribed and claimed.

In the accompanying drawings, forming a part of this specificatiomFigure1 is a sectional elevation of my improved switch stand or box. Fig. 2 isa plan view, portions of the cover and of the vertical shaft beingbroken away. Fig. 3 is a detail view of the vertical shaft. Fig. etis avertical sectional view, the plane of section being indicated by theline IV IV, Fig. 2. Fig. .5 is a view similar to Fig. 4, illustrating amodification of the invention; and Fig. 6 is a sectional elevation on aplane indicated by the line VI VI, Fig. 5.

In the practice of my invention the mechanism except the operating-leveris inclosed within a case or shell consisting of a bottom portion 1,provided 011 opposite sides with lugs or flanges 2, to which the top orcover 3 is secured by bolts 4, said top or cover havinglaterally-projecting flanges 5, whereby the box or case may be securedon the ends of cross-ties or other suitable foundation. Atransmitting-shaft 8 is provided at its ends with journals 7 and 14, thejournal 7 being arranged within a socket or step-bearing 6, forming thebottom portion of the box or case. The upper journal 14 is arranged insuitable bearings in the top of the case or cover, and a spindle 14 forthe reception of the target and lamp extends from the upper end ofjournal 14 of the'shaft. The portion of the shaft within the case orshell is provided with laterally-projecting walls or wings 11, withwhich an inclined member extending from a radial arm on theoperating-shaft, as the arm 10, engages, so that on the laterallyshifting of said arm the shaft will be axially rotated. It is preferredthat an antifriction-sleeve 10 should be loosely mounted upon theportion the driving-shaft 18, which is shown withits' journal portionarranged in suitable bearings 19, formed partly in the lower portion ofthe case or shell and partly in the cover. An operating-lever 21 isconnected with the outer end of the shaft 18, preferably in the mannerdescribed in the application above referred to, in order that ahand-lever 21 can have a movement of approximately ninety degrees or toa vertical position before any consider-' able exertion is required toshift the switch.

The shaft 8 is provided with an arm 23, extending laterally therefromand adapted to be connected to the switch-rod 24, preferably by means ofa pin 25, as described in the application referred to, said pinextending into a slot inthe switch-rod, as shown.

It is characteristic of the construction shown in Figs. 1 to 4:,inclusive, that the arm 10 is simply in engagement with the wings on thevertical shaft and has no pivotal connection whatsoever therewith, butis free to turn while being shifted laterally, theantifrictionsleevefacilitating such axial rotation or movement betweenthe wings.

In the construction shown in Figs. 5 and 6 the arm 10 is provided with aball 9 at its inner end, and the shaft 8 is constructed as described inthe application referred to, with suitable-shaped socket formed in thesections of such shaft, said sections being held together by the coverof the case or shell.

The arm 10 is rigidly connected to the crankarm 17, so as to movelaterally therewith, but without any axial movement of the arm, and therelative change of position of the arm and vertical shaft 8 necessary insuch lateral movement being permitted by the loose engagement connectionof the arm with such shaft. It will be observed that the arm 10 andcrank-arm 17 form two sides of a triangle the base of which coincideswith the axis of the operating-shaft 18 and that such baseline orprolongation of the axis of shaft 18 forms the axis of rotation of thearm 10 and radial arm 17. It is characteristic of the improvementdescribed herein that the radial arm on the operating-shaft has aninclined connection, as the arm 10, to the vertical shaft and that thisinclined connection is integral with the radial arm in the sense thatsaid connection has no movement relative to the radial arm.

I claim herein as my inventi0n- 1. A switch-stand having in combinationa switch-rod, a vertical shaft connected to the switch-rod, anoperating-shaft having a radial arm and integral therewith, an inclinedconnection to the vertical shaft said connection being at an angle lessthan a right angle to the radial arm, substantially as set forth.

2. A switch-stand having in combination a In testimony whereof I havehereunto set 35 my hand.
